Benefits of technology

This method allows for the simultaneous formation of the container's main body and supplying part, reducing manufacturing costs and complexity while ensuring efficient ink supply to the recording apparatus.

Problems solved by technology

Since the liquid accommodating container includes the ethylene-vinylalcohol copolymer layer, the atmospheric air cannot easily transmit the body of the case.
Therefore, it is not so easy for the air to solve in the liquid.

Embodiment Construction

[0026]FIG. 1 is a perspective view of the ink cartridge 10 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the ink cartridge 10. The ink cartridge 10 is mounted with the ink-jet recording apparatus which ejects the ink to the recording medium such as a recording paper to record, and supplies the ink to the ink-jet recording apparatus. The ink cartridge 10 includes a resin case 20 and an ink accommodating container 100 which is accommodated in the resin case 20 and made of flexible resin. Each of the outer shape of the resin case 20 and the inner space shape of the resin case 20 is rectangular parallelepiped and the resin case 20 is sandwiched between an upper cover 40 and a bottom cover 60. The upper cover 40 and the bottom cover 60 are in a plane symmetry. The shape of the main body of the ink accommodating container 100 is rectangular parallelepiped and holds the ink inside. The ink accommodating container 100 includes a supplying par...

Abstract

A method for direct blow molding including steps of: inserting a blowing jig for blowing air into an inside of a prison; locating the two dies to positions so that the two dies face each other across the parison, wherein two dies have a inner space shape, of which overlapping section with the blowing jig is smaller than the outside diameter of a parison; forming the overlapping section between the parison and the blowing jig, to be smaller than an outside diameter of the parison by using a space between the two dies and the blowing jig when the blowing jig is inserted into an inside of the parison and when the two dies are combined together; and depositing a metal layer to the surface by vapor deposition.

Description

[0001]This patent application claims priority from a Japanese Patent Application No. 2003-294641 filed on Aug. 18, 2003, the contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a method for a direct blow molding. More particularly, the present invention relates to a method for a direct blow molding suitable for a manufacturing of a liquid accommodating container.[0004]2. Description of the Related Art[0005]An ink-jet type recording apparatus, which is an example of a liquid ejecting apparatus, does recoding by ejecting ink droplets onto a recording medium from a liquid ejecting head. The ink-jet type recording apparatus includes a liquid cartridge for holding ink, which is detachably mounted on the ink-jet type recording apparatus. The liquid cartridge supplies ink to the liquid ejecting apparatus while mounted on the liquid ejecting apparatus. US Laid-open patent application No. 2002...
